I thought the 323's have the ZF transmission? Guess it depends on build date...Solenoid fix is for the GM's.

But, if you do have the GM, I would say the solenoid being replaced and you still have the symptoms is not a good sign for me or for you.... I think options are new valve body/ cleaned valve body,,,

I think if after replacing my solenoid, if I still get the reverse failure, I am probably going to shift it, as they say on Wheeler Dealers, and get a different car.

Yes my 9/99 build date has the GM tranny... according to the BMW dealer whom replaced all the solenoids in my tranny. Actually while I did experience probably 6 total no-reverse problems in April and May I haven't had an occurrence since.....and I am aware how often I use reverse these days...a lot everyday. This was the solution for me.
